The Thai - Burmese ill will goes back centuries with the refugee flight from Burma giving the Thai the advantage. Thai businessmen (usually Thai-Chinese) are among the worst outside China itself. Not an ounce of compassion when it comes to money. In Phuket or other coastal or island cities you can get seafood caught by local fishermen and it’s fresh.
I wonder what the poor people in these countries would be doing if they were NOT working in factories like the ones described.
